Britt murdered Ms Spence at their Reid unit in September 2022 over two days. A post-mortem examination revealed fractures to her ribs and lower back, as well as bruising, cuts and other injuries covering 40 per cent of her body.
At his sentencing hearing, Britt gave evidence and admitted that the attacks amounted to torture. He said he intended to 'punish her' because he was angry Ms Spence had 'lied' and 'deceived' him. When asked if he was 'in a rage', Britt answered, 'I was'.
Britt pleaded guilty to murder in February this year, three years after his arrest, on the day his two-month trial was due to begin. He said he pleaded guilty as he 'intended to at least cause serious harm', but denied he intended to kill Ms Spence.
The court heard Britt had assaulted Ms Spence twice before during their 12-month relationship. In the lead-up to her death, she had been away from the home for six days and changed her phone number.
ACT Director of Public Prosecutions Victoria Engel SC told the hearing Britt took photos of Ms Spence at various stages during the attacks. She suggested he took the images because he 'was intent on not letting her leave him' and wanted to show her 'how bad it would get if she left for good'. Britt denied he intended to use the photos as a future threat or warning.
The sentencing hearing continues.
